Abstract (en)
[origin: CA2918394A1] A ventilation system (2) for an operating room accessible to service personnel in a nuclear plant, in particular a control room (4) in a nuclear power plant (6), is intended to enable a supply of decontaminated fresh air at least for a time span of a few hours in the event of serious incidents involving the release of radioactive activity. In particular, the content of radioactive inert gases in the fresh air supplied to the operating room should be as low as possible. For this purpose, in accordance with the invention the ventilation system (2) is equipped with an air supply line (10) passed from an external inlet (14) to the operating room, with a first fan (12) and a first inert gas adsorber column (e.g. 38) being connected into said air supply line (10), an air discharge line (44) passed from the operating room to an external outlet (72), with a second fan (46) and a second inert gas adsorber column (e.g. 48) being connected into said air discharge line (44), and switchover means for interchanging the roles of the first and second inert gas adsorber columns (38, 48).
